Forgive me for being somewhat sceptical about the BHCC measurements but I think they are nothing more than a wet finger in the air.
With a traditional (commercial?) system has a fixed amount of hardware that is able to connect to a fixed amount of services etc. If you need to have more inbound calling capacity you buy ore phone lines and cards to drive the lines. If you have more users you buy more phones and cards to drive the phones. In the later VoIP models you buy more licences for whatever thing you require. The result is the same; the additions you make are within the runtime parameters of the underlying hardware. With Asterisk type VoIP systems we have no known limits either in hardware or licences. We can add ten thousand users to a single Gumstix if we chose to. Our limiting factors are such things as network bandwidth, CPU usage, RAM etc. We use off the shelf hardware to emulate something that has been built bespoke. Or am I talking out of my arse here? It has been known ;-} Mark On Sat, 2006-08-26 at 21:58 -0700, Tom Lynn wrote: > Mark, > Is there any way to use this data to compare Astlinux to commercial > PBX systems?
